That would be amazing for many sports, I think. Gamers are used to ghosts in races showing them what others have done. Doing this for real-life sports could really change how people train.
Personally, I find this a very inspirational idea.

Strava live segments kind of do this already and it's more of a curse during training. The hardest part of training for running, aside from the consistent long hours, is taking it easy most of the time. Strava segments cause you to compete with yourself and others and go too hard. This quickly leads to burnout and injury. Slow, consistent runs are what you need during training, and a GPS watch can already give you that.
I won't argue that nobody will use it incorrectly. In fact, I'm positive that it'll happen just like you say at first.
And then the internet will be flooded with bloggers talking about how everyone is doing it wrong since they're now self-proclaimed experts, repeating the same things they've heard someone else say.
And eventually, most people will get on the right track with it. It'll be a "GPS watch" in their head that's far more effective.
And I'm sure people will take it beyond that in ways that neither of us are prepared to imagine yet.
